Improvement in saws



UNITED STATES PATENT OEEIGEc STEPHEN H. VOSBURGH, OF OWEGO, NEW YORK.

IMPROVEMENT IN SAWS.

Specification forming part of Letters Patent No. 154,104, dated August 11, 1874; application filed November 26, 1873.

To all whom it may concern:

Be it known that I, STEPHEN H.VosBURGH, of Owego, in the county of Tioga and State of New York, have invented a new and Auseful Improvement in Saws, of which the fol lowing is a speccation:

The object of my invention is to arrange sawteeth so that the saw will cut faster and yet avoid chattering and jumping, and it is done in the following manner:

In the rst place, for a cross-cut saw, I divide a section of eleven teeth into sixty-six degrees, andregulate the distance from point to point, as follows: Starting from the clearing-tooth a, Fig. l in the drawing, I `make the point of the iirst cutting-tooth six degrees `from the center of the clearing-tooth; the next the saw. In arranging the setting and lin g, the two teeth b b adjoining the clearing-tooth a are set and led alike; the remaining cutting-teeth are set and filed by twos. The width of the clearing-tooth a should be, say, one-fourth the distance to the point of the next tooth.

I am aware ot' patents No. 105,704 and 14,305, and do not claim any construe-tion therein shown; but,

Having thus fully described my invention, what I do claim, and desire to secure by Letters Patent, is

A crosscut-saw provided with sections of ten cutting-teeth, b, each having the clearingteeth a a on each side of them, and arranged at irregular intervals from said clearing-teeth, and from each other in the proportion of six, ve and a half, seven, and five degrees,` al1 constructed as and for -the purpose herein specified.

STEPHEN H. VOSBURGH.
